Kingdom:
The highest category into which organisms are classified and in which the whole of nature could fit.
Phylum:
A category used in the classification that consists of one or several similar or closely related classes. It is known as PHYLUM in classification of animal species and DIVISION in plant species.
Class:
One or several similar or closely related orders. Similar classes are said to be grouped into PHYLUM.
Order:
One or several similar or closely related families. Similar orders form a
CLASS.
Family:
One or several similar or closely related genera. Similar families are grouped into an ORDER.
Genus (pl. genera):
A number of similar or closely related species. Similar genera are grouped into a FAMILY.
Species:
A group of similar individuals that can breed and produce fertile offspring.
Similar and related species are grouped into a GENUS.
